A California premarital agreement can survive every attack a spouse mounts and still lose the one clause the wealthier party cared most about. The spousal support waiver is measured against a different standard than the rest of the document, and it is the provision that fails most often. Under Family Code section 1612(c), a spousal support waiver in a prenuptial agreement faces a second review years after signing, at a moment when the financial picture looks nothing like it did the week before the wedding.
For a founder, a fund partner, or an executive whose net worth sits in assets that did not exist on the wedding day, that second review decides the outcome.
Key Takeaway: California tests a prenuptial spousal support waiver twice. Family Code section 1612(c) makes it unenforceable if the party resisting it lacked independent counsel at signing, and unenforceable if it is unconscionable at the time of enforcement. Property provisions face no second test, so a court can strike the support waiver and still enforce the rest.
Why is the spousal support waiver the most fragile clause in a California prenup?
The support waiver is fragile because it is the only provision in a premarital agreement judged partly on facts that have not happened yet. Every other clause is measured against the circumstances at signing. Section 1612(c) adds a second question asked at enforcement, and no amount of careful drafting in 2014 controls what a marriage looks like in 2034.
Most discussions of California prenuptial agreements treat the document as one object that either holds or does not. A premarital agreement is really a bundle of provisions running on two tracks, and the support track carries requirements the property track does not.
A high earner can win the argument that the agreement was voluntary, that disclosure was complete, that the seven-day rule was honored, that the separate property characterization of a company stands, and still be ordered to pay support.
In our experience reviewing agreements drafted by other firms, the support waiver is usually the shortest paragraph in the document and the one that received the least drafting attention. It is frequently a single sentence of mutual waiver copied from a form. The property provisions run for pages. The drafting effort is allocated backwards from where the risk sits.
What does Family Code section 1612(c) actually say?
Section 1612(c) contains three operative rules, and the third is the one most commonly misstated. The statute provides that any provision in a premarital agreement regarding spousal support, including a waiver, is not enforceable if the party against whom enforcement is sought was not represented by independent counsel at the time the agreement was signed, or if the provision is unconscionable at the time of enforcement.
The statute then adds a sentence most summaries leave out: an otherwise unenforceable provision regarding spousal support may not become enforceable solely because the party against whom enforcement is sought was represented by independent counsel.
Read together, those rules make independent counsel necessary but not sufficient. A support waiver signed by a represented party, after full disclosure, with every procedural box checked, remains vulnerable to an unconscionability finding decades later.
Section 1612(c) was added by Senate Bill 78 (Kuehl), Stats. 2001, ch. 286, effective January 1, 2002. The Legislature passed it in direct response to the California Supreme Court’s decision in In re Marriage of Bonds (2000) 24 Cal.4th 1, which had held that the absence of independent counsel was only one factor among several in assessing whether a premarital agreement was entered into voluntarily. For spousal support specifically, the Legislature converted that factor into a requirement.
How do property provisions and support provisions get tested differently?
Property and support provisions are governed by overlapping but distinct sections, and the differences determine which clause survives. Property terms are tested under Family Code section 1615, which asks whether the agreement was executed voluntarily and whether it was unconscionable when it was executed. Support terms must clear section 1615 and then clear section 1612(c) on top of it.
This is the framework we use when assessing an existing agreement for a client who is contemplating a dissolution.
| Question | Property provisions | Spousal support provisions |
|---|---|---|
| Governing authority | Fam. Code sections 1612(a), 1615 | Fam. Code section 1612(c), plus section 1615 |
| Is independent counsel mandatory? | No. Its absence is one factor in the voluntariness analysis under Bonds. | Yes. Without it, the provision is unenforceable against the unrepresented party. |
| Can counsel be waived in writing? | Yes, under section 1615(c)(1), if the advisement and procedural steps are met. | No. A written waiver of counsel does not save a support waiver. |
| When is unconscionability measured? | At execution only, under section 1615(a)(2). | At execution and again at the time of enforcement. |
| Does full disclosure defeat the challenge? | Often yes. Disclosure is central to section 1615(a)(2). | Not necessarily. Disclosure does not answer the enforcement-date test. |
| Does independent counsel guarantee enforceability? | It substantially strengthens the agreement. | No. Section 1612(c) says counsel alone cannot make the provision enforceable. |
| Typical remedy if the clause fails | May undermine the agreement as a whole. | Frequently severed, leaving the property terms intact. |
The last row matters most for planning. A failed support waiver is usually a targeted loss rather than a catastrophic one.
Why is independent counsel necessary but not sufficient?
Section 1612(c) states two grounds for invalidity in the disjunctive: the provision fails if counsel was absent, or if it is unconscionable at enforcement. Clearing one ground does nothing about the other.
Courts also look past the formality of representation to its substance. In In re Marriage of Facter (2013) 212 Cal.App.4th 967, the party resisting enforcement had technically retained a lawyer before signing. The consultation lasted under thirty minutes, that party never saw the attorney again, and the attorney later testified to having no recollection of the meeting. That representation did not rescue the waiver.
A cursory consultation arranged and paid for at the last minute creates a record that reads as window dressing. Representation that is real, documented, and unhurried is worth considerably more at enforcement than representation that merely existed.
So the wealthier party should insist the other side pick their own lawyer, from their own list, on their own schedule, with the engagement starting well before any draft circulates. Each of those facts strengthens the clause the wealthier party wants enforced.
What are the two seven-day rules in Family Code section 1615?
Section 1615(c) contains two separate seven-calendar-day requirements, and conflating them is a common and expensive error. They measure different things and start at different moments.
The first appears in section 1615(c)(1). The advisement to seek independent legal counsel must be made at least seven calendar days before the final agreement is signed. This rule governs the advisement, not the document.
The second appears in section 1615(c)(2). It requires seven calendar days between the moment the party against whom enforcement is sought was first presented with the final agreement and the moment that party signed. This rule governs the document itself. Both subparagraphs carve out nonsubstantive amendments that do not change the terms of the agreement.
Section 1615(c) sets out three further conditions that must be found in writing or on the record for the agreement to be deemed voluntarily executed. An unrepresented party must have been fully informed of the terms and basic effect of the agreement and of the rights being relinquished, in a language in which that party was proficient, memorialized in writing and delivered before signing. The agreement must not have been executed under duress, fraud, or undue influence, and neither party may have lacked capacity.
The agreement in Bonds was signed the day before the wedding by a party with limited English and no independent counsel. The current statute would resolve those facts very differently.
What changed for prenuptial agreements signed after January 1, 2020?
Assembly Bill 1380 (Stats. 2019, ch. 193), effective January 1, 2020, changed who the seven-day presentation rule protects. For agreements executed on or after that date, section 1615(c)(2)(B) requires the seven-calendar-day period between first presentation of the final agreement and signature regardless of whether the party is represented by legal counsel.
The rule read differently before that amendment. In In re Marriage of Cadwell-Faso & Faso (2011) 191 Cal.App.4th 945, the Court of Appeal held that the then-current seven-day provision did not apply where the party resisting enforcement was represented by counsel from the outset of the transaction. A represented party could sign inside the window.
AB 1380 addressed that holding expressly. An uncodified section of the act states that the addition of subparagraph (B) is intended to supersede the holding in Cadwell-Faso on a prospective basis. A legislature does not overrule a court, and this one did not purport to act retroactively.
That distinction still matters. Cadwell-Faso remains good law for agreements executed between January 1, 2002 and January 1, 2020. For an eighteen-year window of agreements, a represented party’s signature inside seven days is not automatically a defect. For anything signed from 2020 forward, it is.
What does unconscionable at the time of enforcement mean after a long marriage?
No California statute defines unconscionability at enforcement with a formula, and section 1615(b) makes unconscionability a question of law for the court rather than a jury question. What courts examine is the gap between the parties’ circumstances at the moment enforcement is sought, measured against the marital standard of living that Family Code section 4320 makes central to every California spousal support determination.
Duration drives the analysis more than any other single variable. A waiver enforced after four years, against a party whose career never paused, presents a different picture than the same waiver enforced after twenty-two years against a party who left a profession to run a household.
The table below contrasts two hypothetical enforcement postures for an identical waiver clause. These are illustrative scenarios, not predictions, and no outcome in any individual matter can be guaranteed.
| Factor at the time of enforcement | Scenario A: waiver on firmer ground | Scenario B: waiver exposed |
|---|---|---|
| Length of marriage | 4 years | 22 years |
| Supported party’s current earnings | $310,000, career uninterrupted | $0, left a medical practice in year three |
| Supported party’s separate assets | $2.1 million | Under $150,000 |
| Higher earner’s income at enforcement | $900,000 | $4.2 million, plus a $60 million liquidity event |
| Change since signing | Both parties tracked their projections | One estate grew roughly fortyfold; the other did not grow |
| Marital standard of living | Each party can sustain it alone | Unreachable for one party without support |
| Realistic exposure under section 1612(c) | Waiver more likely to hold | Waiver at meaningful risk; property terms still likely enforced |
Wealth alone rarely moves a case from column A to column B. What does it is duration combined with a career surrendered inside the marriage and a standard of living one party cannot approach without support.
What do Facter and Howell show about identical clauses reaching opposite results?
Facter and In re Marriage of Howell (2011) 195 Cal.App.4th 1062 are best read together, because they involve comparable agreements and opposite outcomes. Both concerned waivers in agreements executed before the 2002 amendment. The variable that separated them was the parties’ relative circumstances, not the legal standard.
In Facter, the marriage lasted sixteen years. At signing in 1994, the wealthier party was a law firm partner with roughly $3 million in separate property and annual earnings between $475,000 and $700,000. By the time of enforcement, that separate property exceeded $10 million and earnings had reached about $1 million a year, while the other party had no separate property and no income. Temporary orders in 2011 set spousal support at $21,757 per month. The Court of Appeal agreed the waiver was invalid and described it as presently unconscionable.
In Howell, the picture was reversed. The parties had comparable net incomes when the 1999 agreement was signed, the estate was modest, the twelve-page agreement was not complex, and disclosure was complete. The Court of Appeal held that section 1612(c) does not apply retroactively to agreements executed before its enactment, found substantial evidence supporting voluntariness, and enforced the spousal support waiver.
One point of precision, because it is routinely garbled. Facter did not apply section 1612(c) as its operative authority; the agreement predated the amendment, and Howell had already held the amendment non-retroactive. The court weighed circumstances at the time of enforcement while resting its analysis on the law applicable to a 1994 agreement. For agreements signed from 2002 forward, section 1612(c) supplies the enforcement-date test directly.
Can a court strike the support waiver and keep the rest of the agreement?
Yes, and Facter is the clearest illustration of how that works. The trial court in that case found the support waiver unconscionable and then went further, holding the agreement inseverable and unenforceable in its entirety on the theory that the support waiver was inextricably bound up with the property provisions.
The Court of Appeal reversed that ruling. Reviewing the severance question for abuse of discretion, it concluded that the trial court had erred in failing to sever the invalid provisions from the property rights section. The agreement contained an express severability clause. The property terms survived.
Severability cuts both ways. The downside is that a support waiver can be struck without disturbing anything else, so a party cannot rely on the waiver’s fragility to unravel the whole document. The upside is far larger: a well-drafted agreement can lose its support waiver and still protect a company, a fund interest, a real estate portfolio, and every dollar of separate property tracing.
So draft the agreement so that the support waiver is the only thing at risk, and so that its loss changes nothing else. That means an express and specific severability clause, support terms segregated from property terms rather than woven through them, and no cross-references that let a challenger argue the provisions stand or fall together.
How should a high earner have a spousal support waiver drafted?
The most durable approach is usually not a total waiver. A complete extinguishment of support is the version most exposed to an unconscionability finding at enforcement, because it produces the starkest outcome at exactly the moment a court is weighing fairness.
Graduated structures tend to hold up better. A provision that scales support with the length of the marriage, or that sets a defined term and a defined amount tied to duration, gives a court something to enforce rather than a binary it may be reluctant to impose. A clause that provides nothing after twenty years of marriage invites the exact scrutiny section 1612(c) authorizes.
Several drafting choices carry disproportionate weight:
- Build a real seven-day record for both requirements in section 1615(c), the advisement and the presentation of the final agreement, and document each date in writing.
- Ensure the other party selects and engages counsel independently, early, and without time pressure from the wedding date.
- Attach complete schedules of assets, liabilities, and income rather than relying on a general representation that disclosure occurred.
- Consider a sunset or step structure so the waiver’s effect changes as the marriage lengthens.
- Include an express severability clause and keep support terms structurally separate from property terms.
- Revisit the agreement after major liquidity events, and consider a postnuptial agreement when circumstances have moved far from what the parties contemplated.
Where a marriage is already long and the disparity is already wide, a negotiated spousal support buyout sometimes delivers more certainty than litigating a waiver whose enforcement-date exposure is already obvious.

What drafting mistakes appear most often in high-net-worth prenuptial agreements?
The recurring failures are procedural rather than substantive. They are avoidable at the drafting stage and close to impossible to repair afterward.
Signing too close to the wedding remains the most common. The seven-day clock in section 1615(c)(2) runs from presentation of the final agreement, and a substantive revision circulated four days out restarts the analysis for that version. Couples who negotiate for months and then exchange a materially revised draft during the week of the wedding undo the protection those months built.
Arranging and paying for the other party’s lawyer comes next. It is offered as a courtesy and it reads at trial as control. Facter shows how little a hurried consultation is worth when the record is examined years later.
Incomplete disclosure is more dangerous for wealthy parties than for anyone else, because complex holdings are easier to under-describe. Carried interest, unvested equity, entity interests held through trusts, and contingent obligations all belong on the schedules. When disclosure is challenged later, a forensic accounting analysis will reconstruct what was actually held on the signing date.
Then there is treating the agreement as permanent. A prenuptial agreement drafted when both parties were associates does not fit a household with a nine-figure balance sheet twenty years later.
The last one is a support waiver written as one sentence at the end of a long property document, with no severability clause and no attention to how it will read to a judge who is looking at it for the first time decades after it was signed.
Frequently asked questions about spousal support waivers in California prenuptial agreements
Can a prenup override spousal support in California?
Yes, within limits set by Family Code section 1612(c). A premarital agreement may waive or limit spousal support, but the provision is unenforceable if the party resisting it lacked independent counsel at signing, or if it is unconscionable at the time of enforcement. Both conditions must be satisfied for the waiver to hold.
Do I still have to pay spousal support even with a prenup in California?
Possibly. If a court finds the support waiver unenforceable under section 1612(c), the waiver drops out and support is decided under the ordinary Family Code section 4320 factors. The rest of the agreement, including property characterization, can still be enforced.
What voids a prenuptial agreement in California?
Under Family Code section 1615, an agreement is not enforceable if the party resisting it proves involuntary execution, or unconscionability at execution combined with inadequate disclosure and no written waiver of disclosure. Failure to satisfy the seven-day requirements or the advisement rules in section 1615(c) undermines a finding of voluntary execution.
Can you waive spousal support in a prenup in California without a lawyer?
No. Section 1612(c) makes a spousal support provision unenforceable against a party who was not represented by independent counsel when the agreement was signed. Unlike other terms, a support waiver cannot be rescued by a written waiver of the right to counsel.
How long does a payor have to pay spousal support in California?
Duration depends on the length of the marriage and the section 4320 factors rather than on any fixed schedule. Courts frequently treat marriages of ten years or longer as being of long duration, which affects how long the court retains jurisdiction, as the California Courts self-help guide on spousal support explains. A prenuptial waiver can alter this, if the waiver survives the section 1612(c) tests.
What disqualifies a party from receiving spousal support in California?
There is no single disqualifying event. Courts weigh the section 4320 factors, including earning capacity, the marital standard of living, and each party’s assets. An enforceable prenuptial waiver, a documented history of domestic violence, or remarriage of the supported party can each eliminate or terminate support.
Does a spousal support waiver signed before 2020 follow different rules?
Yes, on the timing question. For agreements executed between January 1, 2002 and January 1, 2020, Cadwell-Faso held that the seven-day presentation rule did not apply to a party represented by counsel from the outset. AB 1380 changed that prospectively for agreements executed on or after January 1, 2020, when the rule applies regardless of representation.
Is a California prenuptial agreement valid without notarization?
Family Code section 1611 requires only that a premarital agreement be in writing and signed by both parties, and it is enforceable without consideration. Notarization is not a statutory condition of validity, though it is commonly used to remove later disputes about signatures and dates.
